PROCESS OF MAKING A COMPOSITION FORUSE IN MATCHES.

1,092,408. I No Drawing. Applicationfiled November Specification ofLetters Patent.

To all whom it may concern:

Be it known that I, HENRY STAIER, a subject of the Emperor of Germany,having announced my intention of becoming a citizen ofth'e United Statesof America, and residing atlNew York, county and State of New York, haveinvented certain new and useful Improvements in Processes of Making aComposition for: Use in Matches, of which 'the'following is aspecification.

The main object of my invention is to prov v'ide an efi'icientsubstitute for yellow'phos- $5 the metallic sulfids in combination withred phosphorus and sulfur. The sulfid em- 'phorusin the manufacture ofmatch-head compositions, such as will'be non-poisonous both in theprocess of. its production, and inits employment as an ingredient inthe.

finaI.'rnatch-head com ound.

Further objects 0 myinvention are to produce a material such as isstable and will 2o.

- 'ment as an ingredient-of the final comnot deteriorate, and which inits employpound, will cause the latter to ignite under friction at a lowtemperature, and to be substantially non-explosive.

"Tog-the foregoing ends I employ one of ployed may be iron,zinc,'copper, antimony, or other sulfid, as may be desired; and'theproportions of the materials may be varied considerably. So far I havefound that the following proportions (by weight) give good results, towit: parts metallic sulfid,

Fahrenheit in a closed vessel.

6 parts red phosphorus, ,3 parts sulfur.

Inycarrying out the process, I thoroughly mix the'tbree ingredientstogether 'and heat them to a temperature of about 500 degrees themixture thoroughly with hot, preferably boiling, water, then draw offthe surplus water and dry the'remainder, the product resulting being adark gray powder. I then employ this product as a match-head compoundingredient in place of the yellow phosphorus commonly employed, mixingit .with one or more mert friction and binding elementssuch as powderedglass, whiting, and glue, or other-ingredients such as are I then washcommonly employed in the production of such compounds, and the finalcompound may be applied to splints or stems in the usual or any desiredmanner.

The foregoing composition is what is. kIIOWII-HI the match trade asnon-poisonous,-

that is to say, it is not poisonous to the subjected to its fumes.Furthermore the 'metallic sulfid red phosphorus and sulfur compound, isstable and will not deteriorate, even 1f kept for a considerable timebefore being employed as an ingredient of the'final compound. The finalcompound will ignite readily under friction, the required tem peraturebeing around 150 degrees Fahrenheit, and ignition takes place quietlyand non-explosively.

What I claim is:

1. The herein described process of producing a substitute for yellowphosphorus in the manufacture of match compositions which comprisesthoroughly mixing red phosphorus, metallic sulfid, and'sulfur andheating the mixture to a temperature of about 500 degrees Fahrenheit.

2. The herein-described process of producing a substitute for yellowphosphorus Patented Apr. 7,1914. I

16, 1910, Serial No. 592,597. Renewed. September 19, 1913. Serial No.790,781.

workmen .who are handling it or who are in the manufacture of matchcompositions which consists in thoroughly mixing red phosphorus,metallic sulfid, and sulfur and heating the mixture to a temperature ofabout 500 degrees Fahrenheit, then washing themixture with water at ahigh temperature. and then removing the surplus water and drying theproduct.'

3. The herein described process of producing a-substitute for yellowphosphorus in the manufacture of match compositions which comprisesthoroughly mixingred phosphorus. metallic sulfid and sulfur in theproportion by weight ofsix parts of red phosphorus, two parts of,metallic. sulfid,

and three parts of sulfur, and heating the mixture to a temperature ofabout 500 degrees Fahrenheit.

.4. The herei described process of producing a substitute for yellowphosphorus Q 1,092,4os

in the manufacture'of match compositions which comprises mixing redphosphorus, metallic sulfid, and sulfur in the proportion by weight ofsix parts of red phosphorus, two parts of metallic sulfid and threeparts of sulfur, heating the mixture to a temperature of about 500degrees F ahrenheit, then ashing the mixture with water at a hightemperature and then removing the surplus water and drying the mixture.
